Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a hair curl dryer having a rotatable hair curling body.

[Conventional technology]

Conventionally, this type of hair curl dryer is disclosed in, for example, Japanese Utility Model Publication No. 57-3523 (first conventional example) and Japanese Patent Application Laid-Open No. 57-84005 (second conventional example).
It is publicly known as. In the curl dryer shown in the first conventional example, as shown in FIGS. 8a and 8b, the core cylinder 2 is fixedly fixed to the hot air discharge side end of the main body case 1, and the hair is wrapped around the outer periphery of the core cylinder 2. A cylinder 3 is rotatably fitted around a core cylinder 2. and,
The core body 2 is formed to have a cross-shaped cross section to form a hot air flow path 30 that allows hot air discharged from the main body case 1 to flow in the axial direction between the core body 2 and the inner surface of the hair body 3.
Hot air is blown out from the hot air passage 30 to a hot air blowing hole 16 provided on the circumferential surface of the hair curling body 3. Further, a push button 22 is attached to the tip of the lead cylinder 2 to prevent the rotation of the hair wrapping cylinder 3 in normal conditions, and when the push button 22 is pressed, the hair wrapping cylinder 3 can freely rotate. Thus, when winding hair around the hair wrapping body 3, the hair is wound around the hair wrapping body 3 by simply holding the main body case 1 and rotating the entire body without pressing the push button 22. After blowing hot air onto the hair on the hair curling body 3 for a predetermined period of time to give curls to the hair, the hair curling body 3 can be rotated freely by pressing the push button 22, and by pulling it in one direction. 3, the hair can be quickly removed. Therefore, it is easy to use since it is not necessary to unwind the hair while rotating the main body case 1 after curling.

Also, in the second conventional example, as shown in FIGS. 9a and 9b, the hair wrapping cylinder 3 is made rotatable with respect to the outer circumferential surface of the core cylinder 2, and the push button 22 provided at the tip of the hair wrapping cylinder 3 is made rotatable. When pressed, the curling cylinder 3 becomes free to rotate, and the hair can be quickly removed from the curling cylinder 3 after curling.

[Problem that the invention attempts to solve]

However, in the first conventional example, the hair wrapping body 3 is easily deformed and damaged by external force.The hair wrapping body 3 originally has a large number of hot air blowing holes 16 and has a porous wall structure with weak strength. Moreover, the cross-sectional shape of the core body 2 is cross-shaped, and the inner wall of the hair-wrapping body 3 is slightly supported at both ends of the cross-shaped rib piece 31 in the longitudinal direction. Therefore,
When accidentally dropped or hit against another object, a portion of the porous wall not supported by the rib pieces 31 of the hair wrapping body 3 is easily deformed and easily damaged.

On this point, in the second conventional example, both the hair wrapping cylinder 3 and the core cylinder 2 are formed in a cylindrical shape and have a double cylindrical wall structure, so the above-mentioned deformation and damage problems of the hair wrapping cylinder 3 are avoided. It can be said that there are few.

However, when a double cylindrical wall structure is adopted as in the second conventional example, although it is excellent in ensuring strength, the following problems occur.

As mentioned above, there is a push button 2 at the tip of the hair wrapping body 3.
2 is attached, and by pressing the push button 22, the hair wrapping cylinder 3 freely rotates around the core cylinder 2,
When the push button 22 is returned, the rotation of the hair wrapping cylinder 3 is prevented, but depending on the timing of returning the push button 22, the hot air blowing hole 1 of the hair wrapping cylinder 3 may be blocked.
6 does not match the hot air outlet 9 of the core body 2 and is blocked by the blind wall part 32 between the hot air outlets 9, 9. In other words, the hot air outlet 16 of the hair wrapping body 3 is not aligned with the body axis. If a large number of long holes are provided in the circumferential direction, the strength of the hair wrapping body 3 will be reduced, and hair will easily enter through the long holes, causing the core body 2 caught between the
For this reason, the number of elongated hot air blowing holes 16 needs to be extremely small, but if this number is small, the rotation stop angle of the hair wrapping drum 3 can be matched with the hot air blowing holes 9 of the core drum 2. Since the position cannot be set in multiple stages, the pushbutton 22 cannot be set as described above.
Depending on the timing of returning the hair, problems such as the hot air blowing hole 16 of the hair wrapping cylinder 3 being blocked by the blind wall portion 32 of the core cylinder 2 are likely to occur. In such a case, if hot air is discharged from the main body case 1 into the core cylinder 2, the heat will accumulate inside the core cylinder 2 and
There was also a great concern that the curling trunk 3 would be deformed by heat.

In consideration of this point, this invention is based on the premise of preventing deformation and damage to the hair roll body due to external force,
In addition, it is possible to prevent thermal deformation of the hair wrapping body and core body, thereby improving safety and durability.

[Means for solving problems]

In order to achieve the above object, the present invention includes a main body case 1 having a built-in heat source 7 and a blower 8;
A core cylinder 2 is fixedly attached to the hot air discharge side end of the main body case 1 and has a plurality of hot air blow-off holes 9 on the circumferential surface, and a core cylinder 2 is rotatably fitted onto the outer periphery of the core cylinder 2 and has a plurality of hot air blow-off holes on the circumferential surface. 16, a cylindrical hair wrapping body 3;
The hair curl dryer is provided with a locking means 18 for switching between a locked state in which the hair curling cylinder 3 is prevented from rotating and an unlocked state in which the hair curling cylinder 3 is allowed to rotate.

Then, the locking means is not activated until the core cylinder 2 is formed into a cylindrical shape on the inner circumferential surface of the hair-wrapping cylinder 3, and the hot air blowing hole 16 of the hair-wrapper cylinder 3 and that of the core cylinder 2 are exactly aligned. Hair roll 3 by 18
In addition to ensuring that a state of rotation prevention is obtained,
Both the hot air blowing holes 16 of the hair wrapping body 3 and the hot air blowing holes 9 of the core body 2 are arranged in a staggered manner, and the number and arrangement thereof are the same.

[Effect]

In such a case, the entire inner circumferential surface of the hair wrapping body 3 is supported by the circumferential wall of the core body 2, so even if the hair wrapping body 3 is subjected to external force due to falling or being hit by another object, it will not be deformed. There will be no risk of damage or damage.

Moreover, heat is not trapped in the core body 2 when the hair body 3 is prevented from rotating, and thermal deformation of the hair body 3 and the core body 2 is also eliminated.

The hot air blowing holes 16 of the hair winding drum 3 and the hot air blowing holes 9 of the core drum 2 are both arranged in a staggered pattern, and by making their number and arrangement the same, it is possible to provide a large number of hot air blowing holes 16 in the circumferential and axial directions of the peripheral surface of the hair winding drum 3 while ensuring its strength, and it is therefore possible to set multiple rotation prevention angle positions of the hair winding drum 3 that can be matched with the hot air blowing holes 9 of the core drum 2.

〔Example〕

FIG. 1 illustrates the overall structure of a curl dryer according to the present invention, which includes a main body case 1, a core cylinder 2, and a curling cylinder 3.

The main body case 1 is formed into a cylindrical shape that is easy to grip.
A discharge port 4 is provided at the tip, and a power cord 5 is provided at the rear end.
and a suction port 6 is provided respectively.
Inside the main body case 1, a heat source 7 consisting of a heater or the like and a blower 8 are arranged in front and behind each other. When the blower 8 is driven, air is sucked in from the suction port 6 and heated by the heat source 7, and then air is heated by the heat source 7. It is designed to be discharged from.

The core body 2 is made of a heat-resistant plastic material and is formed into a cylindrical shape that is thinner than the main body case 1, and has a large number of hot air blowing holes 9 arranged in a staggered manner on its circumferential surface, and a hot air blowing hole at the base end thereof. 11 and a large diameter insertion port 10 are provided. This core body 2 is the insertion port 1
0 is inserted into and removed from the outer peripheral wall of the discharge port 4 of the main body case 1. A push button 12 having an engaging pawl 13 is attached to a part of the outer circumferential wall of the discharge port 4 so as to be freely protrusive and retractable in the radial direction, while a push button 12 that is attached to a part of the inner circumference of the insertion port 10 is engaged when the push button 12 is operated to protrude and retract. By providing a recess 14 into which the mating claw 13 engages and disengages, and by engaging the engaging claw 13 with the recess 14, the core body 2 is fixedly attached to the main body case 1 in a non-rotating manner.

The hair wrapping body 3 is also made of a heat-resistant plastic material and is formed into a cylindrical shape, and has a large number of bristles 15 lined up on its circumferential surface, and a large number of hot air blowing holes 16 are located between the bristles 15. They are arranged in a staggered manner at the same pitch as the hot air blowing holes 9 of the core body 2.

This hair wrapping cylinder 3 is fitted onto the outer periphery of the core cylinder 2 from its tip and is rotatable around the core cylinder 2,
A retaining cap 17 prevents the core from coming off the core body 2, and a locking means 18 prevents its rotation.

Regarding the retaining means, as shown in FIGS. 2 and 4, the retaining cap 17 is formed into a long and short double inner and outer cylinder shape.
a and a short outer cylinder 17b, and the inner cylinder 17a has a pair of locking leg pieces 1 that are elastically deformable in the radial direction around its circumference.
9 and 19 are formed in the shape of notches. This retaining cap 17 has an inner cylinder 17a inserted into the outer periphery of the small diameter tip 2a of the core body 2, and a locking leg piece 1
It is coupled to the tip end 2a of the core body 2 by engaging the claw 19a at the tip of the tip 9 with the hole 20 provided in the tip 2a through its elastic deformation. Thus, the rear end of the outer cylinder 17b of the retaining cap 17 receives the stepped portion 21 formed on the inner circumferential surface of the tip of the hair-wrapping drum 3, so that the hair-wrapping drum 3 is pulled out toward the tip of the core drum 2. to prevent

The hair-wrapping body 3 is especially suitable for the core body 2 when winding hair.
Since the cap 17 is subjected to a strong force of pulling out in the direction of the distal end, the cap 17 does not have to bear the burden of preventing the cap 17 from coming off, but other means are used to prevent it from coming off. That is, as shown in FIG. 4, FIG. 6, and FIG. Rib 2 on the inner peripheral surface of the tip of 3
7 is provided in the circumferential direction, and this rib 27
By positioning the stopper protrusion S on the rear end side and abutting and engaging it, the hair-wrapping trunk 3 is prevented from coming off.

By engaging the rib 27 and the stopper protrusion S to prevent the hair wrapping cylinder 3 from coming off, it is possible to prevent the locking cap 17 from coming off inadvertently, and the hair wrapping cylinder 3 is assembled to the core cylinder 2. It can also be used as a temporary fixing for the hair wrapping body 3.

The locking means 18 may be used, for example, in FIGS. 2 and 4.
A pushbutton 22 as shown in the figure is prepared. This push button 22 is formed in a cylindrical shape, and has locking protrusions 23, 23 formed in the axial direction on its circumferential surface, and a lock pawl 24 projects radially outward from the rear end of each locking protrusion 23. It is set up. On the other hand, grooves 25, 25 are formed on the circumferential surface of the tip end 2a of the core body 2 so as to be located between the stopper projections S, S. In this way, the push button 22 connects the anti-rotation protrusions 23, 23 to the split groove 2 at the tip 2a of the core body 2.
By being inserted so as to engage with 5, 25,
The push button 22 is prevented from rotating relative to the tip end 2a. Further, the push button 22 can be freely moved in and out of the tip portion 2a in the axial direction by a return spring 26 interposed between the push button 22 and the tip portion 2a. Further, on the rear end surface side of the rib 27 of the hair wrapping body 3 that surrounds the outer periphery of the tip 2a of the core body 2, there is a recess 28 in the circumferential direction, into which the lock pawl 24 engages and disengages when the push button 22 is operated. are provided at predetermined intervals (90 degree intervals in the illustrated example). Hot air outlet 9, 16 and recess 28
is set in such a positional relationship that when the lock pawl 24 engages with any of the recesses 28, the hot air outlet 9 of the core body 2 and the hot air outlet 16 of the hair wrapping body 3 exactly match.

In such a case, when the push button 22 is pressed, the lock pawl 24 will be removed from the recess 28, and the hair wrapping cylinder 3 will be free to rotate. When the push button 22 is pushed back by the return spring 26 and its locking claws 24, 24 engage with either of the recesses 28, the rotation of the hair wrapping cylinder 3 is prevented, and the hot air blowing hole 16 of the hair wrapping cylinder 3 is blocked. coincides with the hot air outlet 9 of the core body 2.

The hot air blowing holes 16 of the hair wrapping body 3 and the hot air blowing holes 9 of the core body 2 are both arranged in a staggered manner, and have the same number and arrangement. Therefore, the number of hot air blowers can be increased as much as possible so that the hot air can be blown out evenly from the entire circumferential surface of the hair-wrapping drum 3, and the strength of the hair-wrapping drum 3 can be prevented from decreasing. A continuous blind wall portion can be formed between each hole 16, 16. In particular, the hot air outlet 16 of the hair-wrapping body 3
The rotation prevention angle position of the hair wrapping cylinder 3 that can be matched with the hot air blowing holes 9 of the core cylinder 2 by forming a large number of holes in a small pitch according to the number of hot air blowing holes 9 of the core cylinder 2 is as follows. In the embodiment, the number is set to two per rotation, but it is possible to increase the number to more than this, and depending on the timing of returning the push button 22, the hot air outlet 16 of the hair wrapping body 3 is set to the hot air outlet of the core body 2. Problems caused by being blocked by the blind wall between 9 and 9 can be minimized.

Incidentally, regarding the order of assembling the hair-wrapping cylinder 3 and the push button 22 in the above embodiment, first insert the return spring 26 and the push button 22 into the tip part 2a of the core cylinder 2, and then insert the hair-wrapper cylinder 3 into the core cylinder 2. Insert it, and finally fit the retaining cap 17. In addition, so that the rib 27 can easily pass to the rear side of the stopper projection S when inserting the hair wrapping body 3 into the core body 2,
As shown in FIGS. 2 and 4, a groove 27a is formed by hollowing out the front side of the recess 28 of the rib 27. Further, the bottom portion 27b of the groove 27a is used to prevent the lock pawl 24 from coming off.

[Effect of the invention]

As explained above, according to the present invention, the hair wrapping body 3 can be freely rotated when the locking means 18 is unlocked. The hair can be quickly separated from the hair wrapping body 3 and is easy to use.

In particular, in the present invention, when the rotation of the hair wrapping cylinder 3 is prevented by the locking means 18, the hot air blowing hole 16 of the hair wrapping cylinder 3 and the hot air blowing hole 9 of the core cylinder 2 are always aligned. It is safe because it is possible to prevent an accident in which hot air is trapped in the core body 2 and the hair body 3 and cause thermal deformation therein. In addition, since the core body 2 is formed in a cylindrical shape on the inner circumference of the hair body 3, it is possible to prevent the hair body 3 from being deformed or damaged by external force as much as possible, and to ensure its strength. It's advantageous. Furthermore, the hot air blowing holes 16 of the hair wrapping body 3 and the hot air blowing holes 9 of the core body 2 are both arranged in a staggered manner and have the same number and arrangement. It is possible to provide as many hot air blowing holes 16 as possible while ensuring strength, and the number of hot air blowing holes 9 in the core body 2 increases accordingly.
It is now possible to set the rotation prevention angle position of the hair wrapping cylinder 3 in multiple stages, which can match the rotation angle position of the hair wrapping cylinder 3. This is extremely advantageous in solving the problem of being blocked by a blind wall.
